Wikipedia
Tear gas, formally known as a lachrymatory agent or lachrymator, is a chemical compound that stimulates the corneal nerves in the eyes to cause tearing, pain, and even blindness. Common lachrymators include OC, CS, CR, CN, nonivamide, bromoacetone, phenacyl bromide, xylyl bromide and syn-propanethial-S-oxide (from onions). Lacrymators often share the structural element Z=C-C-X, where Z indicates carbon or oxygen, and X indicates bromide or chloride.
